If this is the only thing that bothers you, get the CVS version of
ocaml: bignum has just be rewritten from scratch, and is now available
under the same license as other libraries.

Funny how Xavier had to rewrite both regexp and bignum just for
questions of license...  the BSD ideal of freely reusable software is
really far away (and ocaml itself is not 100% free either).
(IIRC improving efficiency was another reason in both cases.)

Concerning the discussion 63-bit vs 31-bit, this is not directly
relevant as the ocaml compiler on 32-bit platforms does not put
63-bit integers in the code. At least there could be a warning for
constant overflow.
